fibonacci

What fibonacci does on TinyFn

AI agents call fibonacci to retrieve information from TinyFn without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameters from the server's own tool schema.

Why fibonacci is rated Low

This is a deterministic mathematical utility that only computes and returns data. It performs no write, delete, execute, or financial operations. The tool fits squarely in the Read category as a query-like function that produces output without side effects. Severity is low because misuse by an AI agent would have no harmful consequences—at worst, it generates incorrect or unexpected numeric output.

From the tool's definition The tool name is 'fibonacci' and the description states 'Get the nth Fibonacci number.' This is a pure computational/mathematical function that retrieves or calculates a value without side effects, modification of data, or external operations.

The rule that runs fibonacci safely

PolicyLayer is an MCP gateway: it sits between your AI agents and TinyFn, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For fibonacci, this is the rule to start with:

{
  "version": "1",
  "default": "deny",
  "tools": {
    "fibonacci": {}
  }
}
